A roof replacement in Milliken or Wismer starts from a known baseline: a two-storey house, one layer of builder shingles, and a deck that's usually fine except around the bathroom vents and the skylight if there is one. Berczy's slightly newer houses often have more roof planes and more valleys, which is where the original work was rushed. Cornell is the exception — small footprints with steep, chopped-up roofs, dormers on every side and porches that tie into the main roof at awkward angles; more flashing per square than anywhere else in the city. Unionville's older houses need a different kind of care: steep gables, original wood soffits and fascia that may need repair before new shingles can go on, and chimneys that have to be dealt with at the same time.
The owner inspects the roof and writes the quote from what's there, itemized — shingles, underlayment, flashing, deck repair if needed, disposal. On the day, the roof is stripped to the deck. Any soft sheathing is replaced. Ice-and-water membrane goes along the eaves and valleys — non-negotiable in Markham given how common ice damming is — and synthetic underlayment over the rest. New metal flashing at every chimney, wall and vent. Then architectural shingles, ridge vent, and a check that the soffit intake is actually open so the attic can breathe.
Replace when granules are collecting in the eavestroughs, when tabs are curling on the south slope, when the roof is past 20 years, or when you've had an ice-dam leak two winters running — that last one means the eave protection isn't there and only a new roof puts it in. Repairing a 25-year-old subdivision roof one leak at a time costs more over three years than replacing it once.



Not usually, but they need care. Steep gables and original wood details mean the fascia and soffits are checked and repaired before the roof goes on, and the chimney flashing is often rebuilt rather than reused. We'll tell you what we find.
Yes, and in Markham we usually should. A ridge vent plus open soffits keeps the deck cold in winter, which is the real cure for ice damming, and cooler in summer, which makes the new shingles last.
Most two-storey subdivision houses take one to two days. Cornell's steep, complex roofs and larger homes in Cachet can take three. We give you a date and a realistic window when we quote.
